The skeletal structure in line-angle (line-bond) mode of 2,3,3,5-tetramethylhexane is shown. Identify the number of hydrogen ato

Kruka [31]

Answer:

There are 22 hydrogen in 2,3,3,5-tetramethylhexane (C10H22)

From the left to the right of the skeletal structure:

1st Main Carbon = 3 hydrogen

2nd Main Carbon = 1 hydrogen

1st Branch Carbon = 3 hydrogen

3rd Main Carbon = 2 hydrogen

2nd Branch Carbon = 3 hydrogen

3rd Branch Carbon = 3 hydrogen

4th Main Carbon = 0 hydrogen

4th Branch Carbon = 3 hydrogen

5th Main Carbon = 1 hydrogen

6th Main Carbon = 3 hydrogen

Total = 22 hydrogen

Explanation:

This is the skeletal formula for 2,3,3,5-tetramethylhexane - the 2D chemical structure. It is an organic compound. The carbon atoms in the structure are known as the carbon backbone. The hydrogen atoms are linked to the carbon backbone. This provides each carbon atom with four bonds.

What number should be placed in front of Fe to balance this chemical

andrew-mc [135]

the answer is B. 2

because there is 2 iron on the right side so you need another two on the left side to balance it out

Aniline (c6h7n) has a pkb = 9.4. what are the dominant species present in water if the ph is held constant at ph = 8?

anzhelika [568]

The dominant species present in water if the ph is held constant at ph = 8 is $C_{6}H_{7}N,H_{3}O^{+}$ .

The pH scale is used in chemistry to determine whether an aqueous solution is basic or acidic. Historically, pH stood for "potential of hydrogen." The pH values of acidic solutions are typically lower than those of basic or alkaline solutions.

A solution's pH is a significant indicator of its chemical composition. The pH can affect how readily available nutrients are, how biological processes work, how bacteria behave, and how chemicals behave. The negative log base 10 of the hydronium concentration is used to define pH. The pH is a logarithmic indicator of how many hydrogen ions are present in a solution. Since pH is measured on a log scale, a pH increase of 1 equates to a 10x increase in the concentration of H+ ions.

Read the passage "Ants" in the box below.

Alona [7]

Answer:

C) Carla participated in an artistic activity, while Maurice participated in a scientific activity.

Explanation:

Scientific activities involve making observations, which ultimately leads to the series of steps that aims at solving the observed problem or answering a question that arises from the problem. This is the case of Maurice who is observing and recording information about ants in order to solve a curiosity (about what they feed on).

However, on the other hand, Carla is given a pictorial representation of the ants and what they carry. It is not based on curiosity or to answer a question about the ants but rather for decoration or aesthetic purposes, which is what makes her activity artistic.

A 32 year old immigrant from a patriarchal country is giving birth. As she is delivering the baby, she tearfully confesses to he

Wittaler [7]

She's 32. She can vote. She is entitled to privacy and it would take almost an act of Nature to disclose what she has asked of her doctor.

HIPAA has to do with who can look at medical records. If she doesn't want her husband to see those records, they are locked tighter than a safe on Wall Street.

From what I've read, that ruling has many implications. He is her next of kin. Can he sue if something goes wrong? There are more questions here than answers. Will the records be opened if something does go wrong? Where does freedom from prying eyes end and the good of the commonwealth begin?

If this question is anything but a school question (I'm assuming that is all it is), and somebody needs to act on the answer, for goodness sake consult someone who really knows and is governed by HIPAA. This is nothing to fool around with.
